1、下载svg-sprite-loader

npm install svg-sprite-loader -D  

2、配置vue.config.js

chainWebpack: (config) => {
    config.module.rules.delete("svg");
    config.module
      .rule("svg")
      .test(/\.svg$/)
      .use("svg-sprite-loader")
      .loader("svg-sprite-loader")
      .options({
        symbolId: "icon-[name]",
        include: ["src/assets/svg"],
      })
      .end();
    // ============注入cdn start============
    config.plugin("html").tap((args) => {
      args[0].cdn = cdn;
      args[0].title = pageTitle;
      return args;
    });
    // ============注入cdn end============
  },
  devServer: {
    host: "localhost.longfor.com",
    allowedHosts: [".longfor.com"],
    port: 9001,
    https: true,
    proxy: {
      "/psbr-board-server-uat": {
        target: process.env.VUE_APP_BASE_URL,
        changeOrigin: true,
      },
    },
  },
  css: {
    loaderOptions: {
      stylus: {
        'resolve url': true,
        import: [path.join(__dirname, './src/style/variable.styl')]
      },
      postcss: {
        autoprefixer: {},
        plugins: [
          require('postcss-px2rem')({
            remUnit: '37.5',
            propList: ['*']
          })
        ]
      }
    }
  },

3、封装SvgIcon.vue

<template>
  <svg :class="svgClass" aria-hidden="true" v-on="$listeners">
    <use :xlink:href="iconName" :style="{ fill: color }" />
  </svg>
</template>

<script>
// 使用方式： doc: https://panjiachen.github.io/vue-element-admin-site/feature/component/svg-icon.html#usage
  export default {
    name: 'SvgIcon',
    props: {
      iconClass: {
        type: String,
        required: true
      },
      className: {
        type: String,
        default: ''
      },
      color: {
        type: String,
        default: ''
      }
    },
    computed: {
      iconName() {
        return `#icon-${this.iconClass}`
      },
      svgClass() {
        if (this.className) {
          return 'svg-icon' + this.className
        } else {
          return 'svg-icon'
        }
      }
    }
  }
</script>

<style scoped>
.svg-icon {
  width: 1em;
  height: 1em;
  vertical-align: -0.15em;
  fill: currentColor;
  overflow: hidden;
}
</style>

3、配置svg组件

image.png

// svg组件 用于常用图标引入
import SvgIcon from '@/components/SvgIcon'
Vue.component('svg-icon', SvgIcon)
const req = require.context('@/icons/svg', false, /\.svg$/)
const requireAll = (requireContext) => requireContext.keys().map(requireContext)
requireAll(req)

4、应用

// info就是svg文件名称
<SvgIcon icon-class="info" class="info"></SvgIcon>
